FNM's Filter Testers, including the FT150PA, FT200PO, and FT200PS models, are designed to assess the efficiency and pressure drop characteristics of various flat sheet filter media. These testers utilize oil/salt aerosols or atmospheric dust to conduct the assessments. Our filter testers are versatile tools suitable for evaluating a range of flat sheet media commonly employed in the production of respiratory face masks and air filters.
Filter testers are equipped with high precision particle counter (six-channel particle sizes: 0.3, 0.5, 1.0, 2.5, 5.0 and 10.0 µm) for counting the particles generated by oil / salt particle generator or atmospheric dust in order to calculate filtration efficiency. Additionally, this machine can calculate air permeability and pressure drop of flat sheet media automatically. FT200PO and FT200PS use two particle counters that simultaneously count upstream and downstream particles. Data can be saved automatically and also test reports can be printed by an installed printer on the machine. FNM’s filter testers can measure the efficiency and pressure drop of flat sheet media according to BS EN 143, BS EN 149, BS EN 779, ISO 16890, ISO 16900-3, ISO 11155-1 and ISO 5011 standards. Note: FNM’s filter testers are designed for testing flat sheet air filter media only.
